企鹅同其他生活在寒冷地区的鸟类一样,都已经适应了寒冷的气候,能够尽可能少地散失热量,保持自己身体主要部分温度在40℃左右。但是它们的脚却很难保暖,因为脚上既不长毛,也没有脂肪的防护,而且还有相对较大的面积。 Penguins, like other birds living in cold regions, have adapted to the cold climate and are able to dissipate as little heat as possible, keeping their main body temperatures around 40°C. But their feet are hard to keep warm, because the feet are neither long-haired nor fat-proof, but they also have a relatively large area.
